After skiing the boot a bit last winter while in Italy, I’ve been eagerly awaiting the retail version Synchro (Shadow in women’s version) so we could do an honest unboxing. This is essentially an upgrade of the now venerable Spectre, boasting a clever two piece tongue that flexes while touring and locks for downhill when buckled tight. Scaffo is still constructed with easily customized Grilamid, cuff latch is said to be improved. Overlap liner instead of the Synchro’s tongue liner. Check out a few photos.

Preemptive question and answer: “Lou, can the two piece tongue be swapped to the Spectre?” “Yes, though I have no idea of availability.”
Beautiful shoes. Two piece shell tongue is the significant difference from Spectre. Overlap liner differentiates as well, but is easily swapped for a tongue liner if you’ve got the need and the cash. Works with Trab binding. Grilamid scaffo is easily heat punched. I did ski a pair of these last winter in Italy. They tour better than you’d expect from a tongue shell combined with overlap cuff, meaning with buckles adjusted properly they’re ok but not exceptional. Swap in a tongue liner and the lack of tongue resistance would cross over more to the exceptional category. Rearward cuff travel is good, but actual rearward ankle freedom is limited by the stiff liner. Synchro is plenty stiff on the downhill, progressive feel of flex was what I’d call average for a tongue shell.
